I found a file called /etc/named/pri.0.0.127.in-addr.arpa.

Here's the dig output [specifics replaced with notes in square brackets]:

I think I know the book you mean (one of the O'Reilly ones with an animal on
the front?) and no, I haven't got it - I know I should and I'm sure it's
very interesting - but I suppose I was naive enough to think I wouldn't have
to become expert on that to keep a RaQ4 (nothing special) working...

Any further suggestions gratefully received.

By the way I accidently sent half a message in this thread from the wrong
sender's address so it will surface after moderation. Apologies to the list
in advance.
